Wikipedia lists energy consumption being 70% coal, I'm not sure why the large discrepancy there. I got my information about electrical engines from a website trying to talk up how great it was that we were moving away from oil based engines, but even there they admitted that until more power generation is switched over to renewable that emissions are higher with electric cars. Which makes perfect sense and is not dubious, the fewer times you need to convert energy the less energy wasted. Electricity does not store well, additionally.

- Kequc 9y agoYeah that'd be the link it's the first image on the page.
- sjs382 9y agoThe image/graph you're referencing illustrates "United States total primary energy consumption by fuel in 2015". Total, not electric. You were discussing production of electricity, which is shown in the table I linked on that page to be 32%.

- fastball 9y agoWait, how does that make sense? What kind of energy if not electrical is coal being used to produce?
- mnw21cam 9y agoBlast furnaces, heating, other chemical processes.
- seanmcdirmid 9y agoCoal isn't used for heating much in the US, if at all. It is sometimes used for metal production, especially on the east coast, but oddly, not on the west, where hydro is used.
- greeneggs 9y agoI think the Wikipedia image (at the top of the page [1]) is simply wrong. If you follow the link to the source, [2, page 43], you get 396.3/2280.6 = 17.4% for coal in the US, "Primary energy: Consumption by fuel."
